HV

High voltage outputs.

High voltage push-pull outputs, which, depending on controlling low voltage data, can drive

loads either to a GND, or to V

Data Out

Serial data output

Data output for cascading to the data input of the next device.

19

N/C

No connect.

Polarity

---

22

CLK

Data shift register clock.

Input are shifted into the shift register on the positive edge of the clock.

23

GND

Logic and high voltage ground.

24

VPP

High voltage power rail.

25

VDD

Low voltage logic power rail.

26

Latch Enable

Latch enable input.

When LE is high, shift register data is transferred into a data latch. When LE is low, data is

latched, and new data can be clocked into the shift register.

27

Data In

Serial data input.

Data needs to be present before each rising edge of the clock.
